added fftw3 as fft(library will not versioned, should be in a linkable folder) , did some corrections on the code, splitted main file up (allows use of makefile), added makefile
changes on mpie_spectral.f90:
new structure, changed variable names, now using defgrad instead of disgrad, cleaned up, removed augmented Lagrange.
ToDo: Implement Augmented Lagrange again (but then a working version), implement Large strain, think about complex-to real-transform backwards, try to implement MP-support
